This work investigates the possibility of commercialization of a recently proposed nano calcium carbonate production process as an improved process. The analyzed process uses steel slag instead of limestone as the calcium source to produce nano calcium carbonate and comprises a calcium carbonation process and a NaCl electrolysis process. CO₂ reduction impact and techno-economic feasibility of the system are analyzed to investigate its feasibility. The new process is expected to reduce the CO₂ emission by about 8 %, compared to the conventional process of making the nano calcium carbonate. In addition, unit cost of production for the new process is 484 USD/ton indicating that it is economically feasible. Sensitivity and scenario analyses are performed with respect to the type of electricity sources and the capital cost of the electrolysis system, which are the key contributors to the overall cost.

这项工作调查了最近提出的纳米碳酸钙生产工艺作为改进工艺的商业化可能性。分析的过程使用钢渣代替石灰石作为钙源来生产纳米碳酸钙，该过程包括钙碳酸化过程和NaCl电解过程。分析了CO ₂减少的影响和系统的技术经济可行性，以研究其可行性。新工艺有望减少CO ₂排放与制备纳米碳酸钙的常规方法相比，排放量降低了约8％。此外，新工艺的单位生产成本为484美元/吨，表明该工艺在经济上可行。针对电源类型和电解系统的资本成本进行了敏感性和情景分析，这是造成总成本的关键因素。
